The Mango Suite is a set of three freely downloadable cross-platform authoring programs for flexible network-based CALL exercises. They are Adobe Air applications, so they can be used on Windows, Macintosh, or Linux computers, provided the freely-available Adobe Air has been installed on the computer. The exercises which the programs generate are…

Showcased in the courseware exhibition, "VoiceForum" is a web-based software platform for asynchronous learner interaction in threaded discussions using voice and text. A dedicated space is provided for the tutor who can give feedback on a posted message and dialogue with the participants at a separate level from the main interactional…

Spoken word recognition is achieved via competition between activated lexical candidates that match the incoming speech input. The competition is modulated by prelexical cues that are important for segmenting the auditory speech stream into linguistic units. One such prelexical cue that listeners rely on in spoken word recognition is phonotactics.…

Schools located near to airports are exposed to high levels of noise which can cause cognitive, health, and hearing problems. Therefore, this study sought to explore whether this noise may cause auditory language processing (ALP) problems in primary school learners. Sixty-one children attending schools exposed to high levels of noise were matched…

Purpose: To examine the effect of fundamental frequency (F0) on the intelligibility of speech with flattened F0 contours in noise. Method: Participants listened to sentences produced by 2 female talkers in white noise. The listening conditions included the unmodified original sentences and sentences with resynthesized F0 that reflected the average…

Purpose: The purpose of this study was to examine the effect of the 226-Hz probe level on the acoustic stapedius reflex threshold. Method: Contralateral reflex thresholds for a 1000-Hz pure-tone stimulus were obtained from 40 young adults with normal hearing using an experimental system at four 226-Hz probe levels (70, 75, 80, and 85 dB SPL) with…

Purpose: Past research has established parameters for the 2f1-f2 distortion product otoacoustic emissions (DPOAEs) that enhance response levels (e.g., L1 - L2 = 10 dB; f2/f1 = 1.22; L1, L2 = 65, 55 dB SPL). These same parameters do not optimize 2f2-f1 DPOAEs. Therefore, this study was conducted to evaluate more completely those parameters that…

Researchers in second language acquisition (SLA) have increasingly discussed the role that attention plays in the learning of a second language (L2). This discussion has led to research on proposed pedagogical strategies aimed at directing L2 learners' attention to aspects of the L2 grammar that are difficult to learn or acquire. Research on one…

The goal of this dissertation is to introduce a method for deriving morphemes from Arabic words using stem patterns, a feature of Arabic morphology. The motivations are three-fold: modeling with morphemes rather than words should help address the out-of-vocabulary problem; working with stem patterns should prove to be a cross-dialectally valid…

The present study examined the perception of Mandarin disyllabic tones by inexperienced American English speakers. Participants heard two naturally-produced Mandarin disyllables, and indicated if the two were the same or different. A small native Mandarin-speaking control group participated as well. All 21 possible Mandarin contrasts where the…

The phonetics-phonology interface has long been debated; some linguists argue for a modular approach (Keating 1984, Pierrehumbert 1990, Zsiga 1997, Cohn 1998), while others argue that there is no interface, and that phonetics and phonology are one and the same (Browman & Goldstein 1989-1992, Ohala 1990). Recent proposals by Gafos (2002), and…

This study examined the effect of second language (L2) age of acquisition and amount of experience on the production of word-final stop consonant voicing by adult native Korean learners of English. Thirty learners, who differed in amount of L2 experience and age of L2 exposure, and 10 native English speakers produced 8 English monosyllabic words…

This practical teachers' guide will help you to unlock the enormous potential of new technology in order to enhance pupils' learning, particularly for young people with additional needs. Written by two of the UK's leading technology experts, this new resource will enable you to use ICT effectively to make lessons more accessible, motivating and…

Auditory perception with cochlear implants (CIs) enables the majority of deaf children with normal learning potential to develop (near) age-appropriate spoken language. As a consequence, a large proportion of children now attend mainstream education from an early stage. The acoustical environment in kindergartens and schools, however, might be…
